Hi Keith,
Well you could google for flash animations, or SWF file (swf is the file extension for flash files, Shockwave Windows Flash). However a lot of flash files are compressed. Video Studio will support compressed swf files.
Another consideration is the current flash format, ie; Flash 4,5,6,7,or 8. I'm not sure if VS9 will support the latest. I haven't had a chance to test this with the latest versions (7 and 8 ).
There are numerous flash authoring tools available. The one that I use is
SwishMax It is an affordable and strong competitor to
Macromedia FlashMX the elite flash authoring tool.
Hope that gives you some direction...
Ron
